The silver dial with the elegant hands and markers hit the perfect balance between elegance and functionality. This 5107 watch in 18K yellow gold includes a date and crown guards that emulate the tapered lugs that gives the watch a larger wrist presence. The Patek Caliber 315 movement is rhodium-plated, constructed with 30 jewels, and includes the patented Patek Philippe Gyromax balance with a 21K gold rotor and multiple accuracy adjustments. The automatic movement with solid gold rotor is on display through the sapphire crystal exhibition case back and the movement offers time including hours, minutes, seconds, and a calendar display window. This watch is fitted with a genuine Patek brown crocodile strap and matching 18k signed Patek deployant buckle. While the Calatrava line continues, this particular model has been discontinued, which a person should consider when wondering whether this particular Calatrava is the watch for them as the supply is effectively limited.
